I'm using cfchart tag to draw my line chart in ColdFusion.
My x-axis range is from 1 to 24 and it is fix number of labels for all my charts.
But in my chart, I may have values for first 10 (or any fix number from 1 to 24) points. I mean, my query row count will be 10.
So query with 24 points will show full graph ad query with 10 points will show x-axis values from 0 to 10. But I want to scale the chart for 24 points regardless of query count.
cfchart has an option called scaleFrom and scaleTo to fix the y-axis series, Is there any option for x-axis series?
Following is a chart and it should scale it for 24 points on x-axis (lines from the 10th point will not be there).
<cfchart format="jpg"
xaxistitle=""
yaxistitle="" chartwidth="600" chartheight="120">
<cfchartseries type="line" paintstyle="shade"
query="qChart1" markerstyle="circle"
itemcolumn="CHARTLABEL"
valuecolumn="INTCHART1" />
</cfchart>
I think you are looking for
xAxistype="Scale" scaleMin="1" scaleMax="24"
xaxistype normally defaults to "category" which I believe is simply the query in order, but by setting to "scale" (must be all numeric values) you can alter this.
If you are wanting more custom formatting for charts fire up webcharts.bat in the charting folder of CF and fill your boots.
Saul's answer is more elegant than mine, but I'll still share.
I had the same problem with showing monthly activity for the last year. Sites that had only been active briefly, or who had no traffic/growth/whatever I was tracking didn't display correctly.
Instead of using a cfchartseries displaying a query, I looped over the time to be displayed, used a query of queries to extract the data for that month, and then added a data point for that month.
A bit brute force, but it worked.

I have the following SharePoint Lists:
Plans:
Plan
Curve
Description
Plan001
Curve001
asdf
Plan002
Curve002
asdf
Curves:
Curve
ValueA
MeasureA
ValueB
MeasureB
Curve001
10
100
50
100
Curve002
20
30
40.
80.
A User can select a Plan in Power BI. When the plan gets selected, I want to draw a Visualization of the corresponding curve E.g. when Plan001 gets selected, Curve001 should be drawn. The Points consist of the Values (X-Axis) and Measures (Y-Axis)
I managed to get all the values with either measure column or calculation column. But I am not able to draw the line chart. This is probably because each field in the curve table is also a own column.
The chart works perfectly if I create a table like this from hand:
Value
Measure
10
100
50
100.
Is there any way to transform the table, measure columns or calculation columns to such a table automatically? Or do you know a way how I could achieve this?
Unfortunately, I can't change the SharePoint list.
In a Power Bi report I'm using a Scatter Chart (bubble) with a Play Axis (months).
But this one is limited to 10 elements (I tried years, days, weeks... always 10). Also it's not a size problem, I already tried to put it on maximum size.
And I would like to have 12 elements (all months). How can I fix that?

Thanks a lot
The scatter chart does not limit the play axis to 10 items, the value for those remaining items are null/blank due to which the play axis does not show those values. Please find below the screenshot. So please check the data for those missing categories.
Thanks.
I developed the few Line charts for BMP280 sensor data in powerbi. This is one of the line chart for displaying the temperature value by time and device id.
But I want same line chart with different Color like this below image, whenever temperature value suddenly changes.
Can you please tell me is it possible to develop the Line chart with multiple colors?
If you're willing to consider a vertical bar chart instead of a line chart, you would be able to create a calculation for each row that determines whether the change is significant, potentially by comparing an aggregate of recent measurements to specific thresholds.
Once you do that, you would use this column's value as a legend for your visualization. So if a row has a value of "Significant Positive Change" (or something like that), the bar or bars showing that change can be red.
Your other alternative is to use an R-based visual, of which there are surely examples of this type of visualization. I'll update this answer if I find one that looks promising.
Instead of tending 1 data series, you can split it into 2 data series e.g. one with normal temperatures and one with high temperatures. Then you can just plot these in different colours. Just make sure that the ranges are same i.e. cannot be 'Auto'.
With Power BI line charts there is a limitation of not being able to add more than one "Values" field when a "Legend" field has been defined.
The feature I need is to simply be able to plot a horizontal line based on a measure I calculate via DAX.
Currently the Analytics tab allows to add constant lines based on max/min/avg of Value but doesn't allow to specify a measure from the data model to plot as horizontal line.
Can someone provide a solution or work around to be able to plot additional horizontal lines on line chart?
The reason you can't put a second measure on your chart when you have a legend defined is because the legend creates multiple colored lines out of a single measure. If there were 2 measures, it would expect to convert both measures into multiple colored lines too, and then you'd have 2 lines that correspond to each legend item. Either the chart would have two lines with the same color, or you'd need 2 colors for the same legend item. Neither of which are very clear.
I don't think that's what you're looking to accomplish with a second measure, though. You're looking to add a reference line on the chart based on the second measure, not split the 2nd measure out by the legend. It's a reasonable request.
If your legend isn't highly dynamic and doesn't have too many items, you can create a measure for each legend item.
Say you have a Sales measure and a Sales Category with 5 items (Cat1-Cat5 for simplicity). Create 5 measures, each filtered to one legend item.
Cat1 Sales:=CALCULATE([Sales],'Your Table Name'[Sales Category]="Cat1")
Cat2 Sales:=CALCULATE([Sales],'Your Table Name'[Sales Category]="Cat2")
....
You can then remove Sales Category from your legend, and remove Sales from your Values. Instead, in Values, place the 5 measures: Cat1 Sales - Cat5 Sales. This will make one line per legend item, so your chart shouldn't look too different. However, now you've done that, you can also drag on a 6th measure as your reference line. It's not the greatest solution but it should work as a stop-gap.
In the format section of your line chart, you can also change the data color for each measure e.g. if you want your reference line black and your measures shades of blue.
There are several ideas in the Power BI ideas forum requesting a reference line based on a measure, and I do recommend adding your voice to them too. E.g. https://ideas.powerbi.com/forums/265200-power-bi-ideas/suggestions/15497754-ability-to-dynamically-with-dax-functions-or-meas or https://ideas.powerbi.com/forums/265200-power-bi-ideas/suggestions/13296177-dynamic-reference-lines
I am creating a gvisMotionChart that displays data from the past 5 years. I would like the initial state to be the most recent date (ex. 2012) and for the chart to move "backwards" in time. I know how to set the initial state to the latest date, but that doesn't reverse the time scale at all it just starts the chart at the end of the timeline.
basically, I am looking for a function for the gvisMotionChart that does the same thing as the "hAxis.direction" function for the google Scatter Chart.
Does anyone know how to accomplish this?
Thanks!!
