The column bar is too small. And I couldn't adjust their height. The screen shot is attached here: https://prnt.sc/p09hj9.
I have tried all the methods of column series at https://www.amcharts.com/docs/v4/reference/columnseries/.
am4core.ready(function() {
// Create chart instance
var chart = am4core.create("historical_monthly_chart_range", am4charts.XYChart);
// Push data into the charts
var dateAxis = chart.xAxes.push(new am4charts.DateAxis());
var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());
var series = chart.series.push(new am4charts.LineSeries());
series.name = "Price Range";
valueAxis.title.text = 'Price (S$ psf)';
series.dataFields.dateX = "date";
series.dataFields.openValueY = "min";
series.dataFields.valueY = "max";
series.tooltipText = "{date} \n Maximum: {max} \n Average: {average} \n Minimum: {min} \n Volume: {value}";
// Setting the appearance
series.tooltip.background.cornerRadius = 20;
series.tooltip.background.strokeOpacity = 0;

series.tooltip.label.textValign = "middle";
series.fillOpacity = 0.5;
series.tensionX = 0.8;
series.fill = am4core.color("#697e69");
var series2 = chart.series.push(new am4charts.LineSeries());
series2.name = "Minimum Price";
series2.dataFields.dateX = "date";
series2.dataFields.valueY = "min";
series2.stroke = am4core.color("#697e69");
series2.tensionX = 0.8;
var series_average = chart.series.push(new am4charts.LineSeries());
series_average.name = "Average Price";
series_average.dataFields.valueY = "average";
series_average.dataFields.dateX = "date";
series_average.stroke = am4core.color("#000");
/* Bar chart series */
var barSeries = chart.series.push(new am4charts.ColumnSeries());
barSeries.dataFields.valueY = "value";
barSeries.dataFields.dateX = "date";
barSeries.fill = am4core.color("#000");
barSeries.columns.width = am4core.percent(60);
chart.cursor = new am4charts.XYCursor();
chart.cursor.xAxis = dateAxis;
chart.legend = new am4charts.Legend();
});
There is a bounty on this issue from AM charts however one workaround can be using scrollbar in Y axis like this following:
chart.scrollbarY = new am4core.Scrollbar();
This is not the best solution i agree but you can use it to slightly zoom with the buttons and scale and see
let me know if it works!
I got an attributed string with an image in a textview, the attributed image is displaying fine. The issue is whenever I add the image it replaces the text inside the textview. I want to add the attributed image and then place the cursor at the end of the image, so that i can add text below the image. This is what I tried so far, thank in advance.
let attachment = NSTextAttachment()
attachment.image = selectedImage
let newImageWidth = (textView.bounds.size.width - 10 )
let scale = newImageWidth/(selectedImage.size.width)
let newImageHeight = selectedImage.size.height * scale
attachment.bounds = CGRect(x: 0, y: 0, width: newImageWidth, height: newImageHeight)
let myAttributedString = NSAttributedString(attachment: attachment)
textView.textStorage.insert(myAttributedString, at: textView.selectedRange.location)
I fixed my issue my creating an NSMutableAttributedString() and add a new line attribute to put cursor to the bottom of the image. Hope this help someone.
var mutableAttrString = NSMutableAttributedString()
let attachment = NSTextAttachment()
attachment.image = selectedImage
let newImageWidth = (textView.bounds.size.width - 10 )
let scale = newImageWidth/(selectedImage.size.width)
let newImageHeight = selectedImage.size.height * scale
attachment.bounds = CGRect(x: 0, y: 0, width: newImageWidth, height: newImageHeight)
let myAttributedString = NSAttributedString(attachment: attachment)
let text:[String:Any] = [NSFontAttributeName:UIFont.boldSystemFont(ofSize: 20)]
// Fixed my problem of having image replacing text, instead I place the text at the bottom of the image
let textAttr = NSMutableAttributedString(string: "bottom of image \n", attributes: text)
mutableAttrString.append(myAttributedString)
mutableAttrString.append(textAttr)
textView.attributedText = mutableAttrString
I have an logo that is quite large (58312 x 1478 px), I am reducing the size of it using alamofire image, and then setting constraints to centre horizontally and vertically in the view (self.view) as shown below using Visual Flow Layout (VFL).
With the below constraints the logo is not centred, can someone please advice where I am going wrong.
let viewWidth = self.view.bounds.width
let viewHeight = self.view.bounds.height
let logoView = UIImageView()
logoView.translatesAutoresizingMaskIntoConstraints = false
let logo = UIImage(named: "logo")
let logoSize = CGSize(width: 200.0, height: 100.0)
let aspectScaledToFitImage = logo.af_imageAspectScaled(toFit: logoSize)
logoView.image = aspectScaledToFitImage
self.view.addSubview(logoView)
let logoHeight = logoView.frame.size.height
let logoWidth = logoView.frame.size.width
let logoViewTopSpacing = (viewHeight / 2) + (logoHeight / 2)
let logoViewSideSpacing = (viewWidth / 2) + (logoWidth / 2)
let views = [
"logoView" : logoView
]
// SETTING CONSTRAINTS
view.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "H:|-\(logoViewSideSpacing)-[logoView]", options: [], metrics: nil, views: views))
view.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|-\(logoViewTopSpacing)-[logoView]", options: [], metrics: nil, views: views))
I figured out that
by replacing the below
let imageWidth = aspectScaledToFitImage.size.width
let imageHeight = aspectScaledToFitImage.size.height
let logoViewTopSpacing = (viewHeight / 2) - (imageHeight / 2)
let logoViewSideSpacing = (viewWidth / 2) - (imageWidth / 2)
with
let logoHeight = logoView.frame.size.height
let logoWidth = logoView.frame.size.width
let logoViewTopSpacing = (viewHeight / 2) + (logoHeight / 2)
let logoViewSideSpacing = (viewWidth / 2) + (logoWidth / 2)
Solved the problem of centering the logo inside the view

I'm new to SpriteKit and Swift 3. With a few million speakers there's not a lot of Esperanto software so I want to make a game for myself to learn 1000 Esperanto words. (not shown!)
I want to have each card flip to reveal a word value from the dictionary key/values.
Then see if that word matches the wordGuess label key for the value selected.
Also JSON might be better for breaking up 1000 words into modular sections but I'll cross that bridge at another time.

How to assign dictionary values to the cards?. EDIT 2: By not using values! I'm going to do from the perspective of dictionary keys, that way each card has a key value pair, then just display the value.
// get all the card keys
var cardKeys:[String] = []
for (k,_) in cardsDictionary {
cardKeys.append(k)
}
// slice for only four cards
var fourCardKeys = cardKeys[0...3]
// get 1st value for display
cardsDictionary[fourCardKeys[0]]
So SKLabelNode on touchDown? I'll try it. Also need to flip card so word is not on the image. Lastly compare the pressed card's key to the wordGuess key text. Getting closer
EDIT 3: Update of didMove with split keys and values. Can get the title to be the first key now and I can put the first value on the top left card okay as a test. Progress. Now I just need to either blank out the card on touchDown or find a way to flip it.

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {

let touchLocation = touch.location(in: self)

{
label.isHidden = true

label.isHidden = false
}
Personally, I don't like to use userData, my opinion is that isn't a readable code.
I'd some like to create a custom SKNode like:
class Card: SKSpriteNode {
var value....
var dictionary
etc
}
Another solution, you can create a tuples:
var cardsDictionary: [String:String] = [
"vegetable":"legomo",
"plant":"vegetalo",
"actually":"efektive",
"currently":"aktuale"
]
let cardTopLeft = (node:SKNode, value:Int, type:[String:String])
cardTopLeft.node = SKSpriteNode(imageNamed: "Redcard")
cardTopLeft.value = 1
cardTopLeft.type = cardsDictionary[0]
All SKNodes have a dictionary you can write to called userData. It is an optional NSMutableDictionary, so you are going to have to create it:
cardTopLeft.zPosition = 1
cardTopLeft.size = CGSize(width: 300.0, height: 300.0)
cardTopLeft.anchorPoint = CGPoint(x: 0.5, y: 0.5)
cardTopLeft.position = CGPoint(x:-229, y:-57)
cardTopLeft.userData = ["word":"tree","value","arbo"]
addChild(cardTopLeft)
To use:
let word = cardTopLeft.userData["word"]
let value = cardTopLeft.userData["value"]
Getting a better understanding of your question, I would use SKLabelNode as an alternative.
What you can do is create SKLabelNodes to the cards with the word you want to attach, and mark it as isHidden = true. When you are ready to reveal the word, you just mark isHidden = false
let value = SKLabelNode("arbo")
value.isHidden = false
cardTopLeft.zPosition = 1
cardTopLeft.size = CGSize(width: 300.0, height: 300.0)
cardTopLeft.anchorPoint = CGPoint(x: 0.5, y: 0.5)
cardTopLeft.position = CGPoint(x:-229, y:-57)
cardTopLeft.addChild(value)
addChild(cardTopLeft)
//to reveal it
if let label = cardTopLeft.children[0] as? SKLabelNode
{
label.isHidden = false
}
//to use it
if let label = cardTopLeft.children[0] as? SKLabelNode
{
let value = label.text
//compare value to dictionary of answers
}
You may want to give your labels a name so that you do not have to use children[0], but I will leave how you want to find a node up to you.
I have my chart working ok, however I would like to use a custom step for my vertical y-axis. At the moment it seems to be automatic and is spaced out as below:
1,500,000
3,000,000
4,500,000
I would prefer it to be:
100,000
200,000
300,000
and so on...
Is there any way I can set this, I have looked through all the documentation but can't figure it out.
Here is my code:
var chart = new google.visualization.LineChart(document.getElementById('chart'));
chart.draw(chartData, { width: 1600, height: 900, title: 'Company Performance',
yAxis: { gridlineColor: '#ff0000' },
xAxis: { gridlineColor: '#ff0000' }
}
);
My data is company profit for each week of the year, y-axis is profit, x-axis is the week number.
Hope somebody can help.
Paul
this is how I do it:
var options = {
vAxis: { // same thing for horisontal, just use hAxis
viewWindow: { // what range will be visible
max: 120,
min: 0
},
gridlines: {
count: 12 // how many gridlines. You can set not the step, but total count of gridlines.
}
}
};
all the best ;)
For as far as I know this cannot be done automatically with Google Charts settings.
I've written a javascript function to do this.
To use it you can create a nice sequence that can be used as ticks for the vertical axis:
var prettyTicks = getChartTicks(0, chartData.getColumnRange(1).max);
The line for the xAxis should be changed to apply the ticks:
yAxis: { gridlineColor: '#ff0000', ticks: prettyTicks },
Here is the javascript method to create the ticks. It will create a tick for each value of 10 and if that creates too many ticks then it will do this for each 100 or 1000 etc.
// Creates an array of values that can be used for the tick property of the Google Charts vAxis
// The values provide a nice scale to have a clean view.
var getChartTicks = function (min, max) {
// settings
var maxTicks = 8;
var tickSize = 10;
// determine the range of the values and the number of ticks
var newMin;
var newMax;
var nrOfTicks;
var appliedTickSize = 1;
while (newMin == null || nrOfTicks > maxTicks) {
appliedTickSize *= tickSize;
newMin = Math.floor(min / appliedTickSize) * appliedTickSize;
newMax = Math.ceil(max / appliedTickSize) * appliedTickSize;
nrOfTicks = (newMax - newMin) / appliedTickSize;
}
// generate the tick values which will be applied to the axis
var ticks = new Array();
var i = 0;
for (var v = newMin; v <= newMax; v += appliedTickSize) {
ticks[i++] = v;
}
return ticks;
}
So to summarize, after adding this method your code could then be changed to:
var prettyTicks = getChartTicks(0, chartData.getColumnRange(1).max);
var chart = new google.visualization.LineChart(document.getElementById('chart'));
chart.draw(chartData, { width: 1600, height: 900, title: 'Company Performance',
yAxis: { gridlineColor: '#ff0000', ticks: prettyTicks },
xAxis: { gridlineColor: '#ff0000' }
}
);
Hi Please refer google chart api.There are several parameters available according to your requirement like
chbh = Bar width and spacing ...
chco = Series colors ...
chd = Chart data string...
chdl,chdlp, chdls=Chart legend text and style...
chds Scale for text format with custom range...
chem = Dynamic icon markers...
