Hi,

I am a bit confused on how to define a specific color for to a series.

Objective 1: I have a line chart with 20 series. I would like to give half the series a specific color.
Objective 2: If a color is auto assigned (as it is currently), I would like to obtain the colour value and assign it to a second series. For example something like: setSerieColor( "Serie2", getSerieColor("Serie1") ); Is there something like that or is there a workaround?

Thanks for your help,

Stefan

The colors aren't random. They are actually defaults. The way you associate colors with series is to either use one of the existing pallette's or to create your own pallete file, and then use that pallette. The Pallete files are very simple -- just a list of RGB colors, so setting up your own pallette is probably what you want, given your intention to have particular series be specific colors. The series will get the colors you define in your pallette file in the order in which you defined them.

Hi gizmola,

thank you for your reply. So the palette is the only way to assign colours? I guess if I would like to dynamically assign colours and also maybe two data series with the same colour, I would have to automatically generate a new palatte and assign the series in a specific order to do this?

Best wishes,

Hi Stefan,

You can use the setPalette() function to assign colors to a specified data serie.

Kind regards,

Hi Jean-Damien,

thank you for your replies!

Is it possible to include a function like getPalette to get the colour of a specific series? That wayI can use the built in function of assigning default colours but also see what colour has been assigned to a specific series so I can reassign it as well. So I leave all colour management up to the original settings.

Best wishes,

Stefan

I will do it ;o)

Hi,

Just added the getSeriePalette() method to the pData class. (getPalette was already defined for internal use). Using it you can now copy the palette of one serie and replace it to another one :



I've also modified the setPalette() method so it can accept an array of series as 1st argument :



This change will be published in the 2.1.1 subversion.

--Thanks for your suggestion ;o)

Kind regards,
JD.
