Is there a way to change the color and font in case of Tag cloud chart?

@fightaadeshfight
Can you elaborate, please, how do you want to apply colors and font? According which value/condition? Many options available here.

[fightaadeshfight]

Like right now the text is picking random colors. I wanted to create my own set of colors which will be picked at random(there is no condition for it). I just want different shades.

For font i just want a different font for the complete chart.(Again, no conditions applied.)

You can define your own custom palette and the tag cloud will take colours from that palette.
You can implement it like this:

OrdinalColor ordinalColor = new OrdinalColor();
ordinalColor.setColors(new String[] { "#000000", "#f18126", "#3b8ad8", "#00ff00", "#ff0000" });
tagCloud.setColorScale(ordinalColor);

Font you can apply like this:

TagCloud.getNormal().setFontFamily("Helvetica");
tagCloud.getNormal().setFontSize(8);
tagCloud.getSelected().setFontStyle(TextFontStyle.ITALIC);

Can i add my custom font family(like in the form of ttf or otf file in android) or i can only choose from the ones already defined?

@fightaadeshfight
Yes! Now it's possible.
You can do it like this:

anyChartView.addFont("Pacifico", "file:///android_asset/Pacifico.ttf");
tagCloud.getNormal().setFontFamily("Pacifico");

And the Pacifico.ttf file should be located in assets.

We have just updated the library to implement this feature. Please, download the latest version to enable this feature.

Do i need to download the jar file? The new dependency does not seem to work

[Shestac92]

@fightaadeshfight
Can you specify how you include dependencies? With Gradle or any other tool?

[fightaadeshfight]

with gradle. The old dependency
compile 'com.github.AnyChart:AnyChart-Android:0.1.9'

is working fine.

But when i change it to new version it stops working.

@fightaadeshfight
ok, I see. Can you share with us the error log by Gradle?

[fightaadeshfight]

its working now. it wasn't a few hours earlier. maybe the mirrors were not updated or something. Thanks anyways.

I gave the ordinal colors as you said

 OrdinalColor ordinalColor = new OrdinalColor();
    ordinalColor.setColors(new String[] { "#3A3042", "#DB9D47", "#FF784F", "#5BC0EB", "#3C91E6", "#325060", "#6E8898", "#9FB1BC", "#E6EDE9", "#E2C044"});
   
 
    cloud.setColorScale(ordinalColor);

But it picks a 4 colors for the big words. rest are same. Is there a limit to colors that i can give? And if the items in the list is around 10 only one color is shown.

[fightaadeshfight]

I figure it out. The colors were distributed according to category. So if i do not define any category the colors get distributed via range. So, i defined an array of categories and added them at random and hence the colors were chosen at random.
