Can somebody please tell me how can i show the Total Collection on MSChart
You can use chart.Annotations property to get a similar result.
For example with the following code (located after filling the chart):
var ann = new RectangleAnnotation();
ann.Text = "Total Collection" + Environment.NewLine + "250 Billion";
ann.IsMultiline = true;
ann.AxisX = this.chart1.ChartAreas[0].AxisX;
ann.AxisY = this.chart1.ChartAreas[0].AxisY;
ann.AnchorX = 9; // as you can see from the image below,
ann.AnchorY = 41; // these values are inside the range
// add the annotation to the chart annotations list
this.chart1.Annotations.Add(ann);
I got the following result:
N.B.:
there are a lot of annotations types (CalloutAnnotation, EllipseAnnotation...) and they have a lot of properties to change styles and behaviors. You can even set a property to allow annotation moving (i.e. AllowMoving=true).
Have a look to annotation properties through intellisense or MSDN.
You can set the property IsDockedInsideChartArea to true. You will also need to specify which ChartArea the legend is docked to, and set the position property to Auto.
legend.IsDockedInsideChartArea = true;
legend.DockedToChartArea = "ChartArea1";
There are more information about this and other legend properties here.

It is necessary to get/set the value of the vertical speed property. The verticalSpeed property has a value of 500 (the maximum value of the slider), but in OBS I manually set 35.
How to get exactly the value 35?
A second question, how can I see all the available filter properties?
obs_data_t* source = obs_get_source_by_name("SOURCE_NAME");
obs_data_t* filter = obs_source_get_filter_by_name(source, "FILTER_NAME");
obs_data_t* settings = obs_source_get_settings(filter);
vspeed = obs_data_get_int(settings, "verticalSpeed");
Thank you for any help!
Ok, there is an GetSourceFilterInfo function that returns a list of filter properties.
Speed is a parameter speed_x and speed_y.

I'm using google chart API to draw an area chart.
The chart represents an altimetric profile and when I pass the mouse over it, it shows the position (lat and long) from the underlying data table.
So I created my chart:
data = new google.visualization.DataTable(json);
chart = new google.visualization.AreaChart(document.getElementById("chart-output"));
and draw it:
chart.draw(data, options);
and add an handler for the mouseover event
When the event triggers, I want to get the row from the underlying data source
if (event.row != null && event.column != null){
//data is the chart datasource
var o = data.D[event.row];
var sel_x = o.c[0]["coords"]["x"];
var sel_y = o.c[0]["coords"]["y"];
... //show x, y
}
The point is that when the project was first released, last year, everything worked fine and the property data.D actually contained the desired value.
But now, I've found that the same property is undefined and the rows array is found in property data.tf.
I would expect to gain access to the datasource rows through a getter method, but I cannot find the right one. The datatable method ǵetRowProperties(rowIndex) does not provide any content.
What am I doing wrong?
Thanks and regards

Thanks for yr reply, but it's a bit more complicated than that.
My datasource is like this:
{"cols":
[
{"id":"distance","label":"Distance","type":"number"},
{"id":"asfaltocemento","label":"Asphalt/Beton","type":"number"},
{"id":"rocciaghiaia","label":"Fels/Schotter","type":"number"},
{"id":"ghiaccio","label":"Eis","type":"number"},
{"id":"terraprato","label":"Erde/Wiese","type":"number"},
{"id":"sassolastricato","label":"Stein/Pflaster","type":"number"},
{"id":"sconosciuto","label":"Unbekannt","type":"number"}],
"rows":
[
{"c":[{"v":0,"coords": {"x":1296400.1245177952,"y":5885847.104437432,"z":1345.275458520788,"segment_no":0}},{},{"v":1345.275458520788},{},{},{},{}]},

When I get the event from the graphic, I retrieve the needed values this way:
var o = data.tf[event.row];
var sel_x = o.c[0]["coords"]["x"];
var sel_y = o.c[0]["coords"]["y"];
I know it's not a good practise to use property (tf) and I should use accessor like getValue(), but using the getValue method I can't access 'coords' object and its subobject.
Any help will be appreciated
Well, data.d is not a public method, so google can make changes to that, you should use public methods instead for consistency.
Try this:
var sel_x = data.getValue(event.row, 0); // supposing your x value is in fisrt column
var sel_y = data.getValue(event.row, 1); // supposing your y value is in second column

I'm using the Google Visualizations gauge on a page, but it's important that the value its displaying is not shown as a label right below the needle.
I've found two ways of doing this. Once you navigate through the DOM to the gauge widget, and navigating into the SVG pieces, you can either set the textContent element to be an empty string, or you can delete that whole text label entity, entirely.
function removeLabel(widget) {
var gauge_label_parent = widget.getElementsByTagName("g")[1];
var gauge_label = gauge_label_parent.getElementsByTagName("text")[0];
gauge_label.textContent = "";
// Another way of getting rid of the text: remove the element
// gauge_label_parent.removeChild(gauge_label);
}
The problem is: both of those techniques work only on the first time. If I re-draw the gauge with updated values, then the label re-appears, and trying to remove the label element or set textContent="" does nothing.
So, instead of just being able to update the value with:
data.setValue(0, 1, newValue);
chart.draw(data, options);
I have discovered that I have to change the options a little bit, like:
data.setValue(0, 1, newValue);
options.minorTicks = 3; // Change the options somehow
chart.draw(data, options); // Tell gauge to draw that
options.minorTicks = 2; // Change the options back to what they were
chart.draw(data, options); // Draw again
Here's a fiddle to see how it works or doesn't. Set the fixLabel to true or false depending upon whether you want the label problem to be present or not. Keep in mind that the label will (properly) be missing the first time. It re-appears when you update its value.
http://jsfiddle.net/jemenake/72dMt/2/
So, a few questions:
Any idea why it's doing this?
Is there a way to remove the label without having to go through this option-changing business?
Bonus question: Am I unclear about how minorTicks is supposed to work, or is it broken? The docs say that it's supposed to be the number of minor ticks between majors, but setting it to 2 gives me only 1 minor tick, 3 gives me 2, etc. And, if I set it to 0 or 1, I get "Problem parsing d=''" in the console.
Adding to Madthews answer:
To those of you who are trying to remove the label from the Google Gague Chart.
If you add the following code into your page (i have placed it in the header to keep things tidy) then you can set the font size of the Label to whatever you want.
<style>
* {text-rendering: optimizeLegibility; font-size:100%;}
svg g g {font-size:0px;}
</style>
I have been toying around with this for a while now and the top line of the css above is essential otherwise it will not work!
Ok I'll try to answer:
1) Label options are not managed by current API release
https://google-developers.appspot.com/chart/interactive/docs/gallery/gauge
Workaround: try with this CSS
svg g g {
font-size:0px;
}

Above fiddle explains you the meaning of the minorThicks. It's correct that if you set 2 you get 3 "spaces". Minor thicks represent the number of "BLANK" spaces between two major thicks. In the example you will se the perfect matching between your arrow and the thin line representing the minor thick.
Instead of messing with styles, you could just insert the value with a blank formatted field.
var data = google.visualization.arrayToDataTable([
['Label', 'Value'],
['Unitless Indicator', {v:counter, f:''} ]
]);
This also works with addRows.
jsfiddle here: https://jsfiddle.net/08x2m4vo/2/
Use this. This is also labelled by Google.
var data = google.visualization.arrayToDataTable([
['Label', 'Value'],
['', {v: <Your_own_value_of_the_gauge_meter>, f: ''}],
]);
In place of "<Your_own_value_of_the_gauge_meter>" use your value variable. That's it.
What about this?
['Label', 'Value'],
['', 80]
I have a list of products and I am trying to alternate the colour between each product (grey, white, grey, white, and so on). I understand how to use colour formatting based on a condition such as the following link: example followed. However I dont know how to get it to look at the previous line on the report and check whether it holds the same product name. If it does, then colour the row the same colour, else the alternate colour.
I've setup an example report in the application: Application 67666 - Colour Row by Product example. I have two products in the report so I'm trying to get 3 grey lines and then 3 white lines, if I had more products it would then go back to grey and so on.

Please could I be directed in the right direction, JavaScript and Dynamic Actions shout out to me as in the example link however its looking at the previous row which is getting me all stuck.
I can't think of another solution than javascript really. There is possibly using lag in the sql, but only to use it to determine where the row color should change. You could use the value of the column in a html expression of a column and put it in a class, but you still need to iterate over it with javascript anyway. So it seems less fiddly to just use javascript.
Inline CSS:
table.report-standard tr.normalRow td{
background-color: green;
}
table.report-standard tr.altRow td{
background-color: red;
}
This will override the default style, but you will need to tune this to your demands. For example, the color change on :hover of the row. I prefer steering the style through assigning classes and then define the rules in css than to directly assign css through javascript (which would place it in style tags, ugh).
Dynamic action: change row colour
After Refresh, Region, Product Report
True action: execute javascript code, fire on page load checked
$('td[headers="PRODUCT"]', this.triggeringElement).each(function(){
var lCurrRow = $(this).closest('tr'),
lPrevRow = lCurrRow.prev(),
lPrevVal = lPrevRow.find('td[headers="PRODUCT"]').text();
console.log(lPrevVal + ' - ' + $(this).text());
//if value on previous row differs from the that on the current row
//then change the class
//if the value didnt change, then use the same class as the previous row
if ( lPrevVal != $(this).text() ){
if ( lPrevRow.hasClass('normalRow') ){
lCurrRow.addClass('altRow');
} else {
lCurrRow.addClass('normalRow');
};
} else {
if ( lPrevRow.hasClass('normalRow') ){
lCurrRow.addClass('normalRow');
} else {
lCurrRow.addClass('altRow');
};
};
})
Check your solution on apex.oracle.com, I implemented it there.
I am using Microsoft's DataVisualization.Charting.Chart, and I have integer values along the X axis, using line-style graphs. However, the chart is adding an extra blank item at the beginning and end of the x-axis, with no value labels to explain what they are.
How can I remove these empty items and make the lines go right up to the ends?
Use the IsMarginVisible property of the xaxis. I believe that will do the trick.
To test this, I changed one of my own charts to be a line chart and then set the value in the code:
ReactivityChart.ChartAreas(0).AxisX.IsMarginVisible = False
Tell me if this is what you were hoping to get or if I have totally misunderstood the question:
(note that I do not have a high enough rep to post this image)

You should set the Maximum and Minimum properties in ChartArea.AxisX, e.g. :
this.chart1.ChartAreas[0].AxisX.Minimum = 0; // if your minimum X = 0
this.chart1.ChartAreas[0].AxisX.Maximum = 100; // if your maximum X = 100
In this way, your chart area will show only the values between Minimum and Maximum.
