You can use Froala Charts to create web applications that include multiple instances of the different charts. However, if you need to maintain a consistent look and feel across the web apps, then you can do that using themes.
You can manually set the cosmetic and functional attributes for each chart in the corresponding JSON file. This can work if you deal with only a small number of charts. As the number of charts increases so does your hassles. That is where the Theme Manager shipped with Froala Charts comes in. You can use the Theme Manager to create centralized theme files (similar to CSS files) and then apply those themes to any number of charts.
In a theme file, you can centralize the following aspects of a chart or gauge:
- Visual appearance (data plot color, font color, font size, etc.)
- Behavior (hover effects for data plots)
- Intelligence (applying different colors to the positive and negative data plots in all column charts that use the theme)
Froala Charts ships with the following predefined themes:
