Is there a way to edit the specific colors of the charts and maps. Seems like I am forced to used a random color ramp. I have changed a layer visualization on ArcGIS Online and the map looks fine, but then if I create another card with a chart, the colors are randomly assigned so the charts colors do not match the map colors.
We do have some ability to change colors and point styles with charts and maps. Currently the customization is limited but we'll expand those capabilities in future releases.
