How to set custom color in ComboChart created in MashUp ?

bcherbonneau — Fri, 13 Jan 2023 15:57:39 GMT

Hi,

I have created a combochart in my mashup following this tutorial :

https://help.qlik.com/en-US/sense-developer/May2021/Subsystems/Mashups/Content/Sense_Mashups/Create/Visualizations/Combochart/create-combochart.htm#anchor-4

Is there a way to set a specific color for each measure, without using a global theme for the Qlik app ?

Thank you

Hi there,

In order to override the default theme color pallet, you will have to set the color properties of the chart from 'auto:true' to 'auto:false' & set 'mode: byMeasure'. This is what the property panel looks like in the native product:

From API perspective, it looks like this (same use case):

Thank you for your reply.

From my understanding, mode: byMeasure allows to set colors depending on the measure value.

That’s not exactly what I want : I want to be able to change the color of all the values of one measure.

For example, if I have one set of bars, and one line, I would like to change the colors of :

- the bars : red (same color for all bars)

- the line : blue

That’s similar to the behavior when “Multicolored” is selected, except I want to customize the colors.

Thanks

Now I understand your question better, thanks for clarifying.

What you need to do is

Use master measures and define the color of those measures first
When defining comboChart from the property panel I can see that you can use "Multicolored" mode and choose "Measure" under the "Use library colors" dropdown. That way it leverages the specific colors you set in step 1. See native property panel:

When examining the chart properties, you see that under color object - auto:false, mode:"primary" (also try mode:"multicolored" instead) and useBaseColors:"measure"

Hi,

Thank you for your time.

Sadly, this is not an option for me, since that would force me to create one master measure for each chart.

I guess I should add more context to what I’m trying to achieve :

My initial goal was to display the “same” chart several times (10+), each time having a specific set of filters applied to it
Since filters are global in Qlik, I can’t achieve this using only one item
This means I would have to create n times the same chart, with a different filter each time
To avoid this (and the maintenance cost it would incur) I had the idea to instead create objects on-the-fly in the mashup, which works great

To be more exact, I use a variable to generate the chart measure formulas, passing the filter values I want as parameters

BUT in this case, I can’t use master measures (correct me if I’m wrong on this one)

I’ve managed to replicate the original object configuration/appearance, it only lacks the colors now…

I have also tried to set the “color” property for the measures (set inline in the “cols” of the combochart), but this didn’t seem to do anything.

See https://help.qlik.com/en-US/sense-developer/May2022/Subsystems/APIs/Content/Sense_ClientAPIs/CapabilityAPIs/VisualizationAPI/combochart-properties.htm

If there is an alternative way to achieve what I’m trying to do, I will gladly take it !

Thank you
