I have a requirement for a chart that I'm trying to implement with FusionCharts. A horizontal bar for each of a dozen or so test cases. The color of a bar at any position along the x axis will be mapped from the functional value f(x) for the bar's test case. In other words: the y-axis is the test cases (one horizontal bar each); the x-axis is the x value; the color of the bar at x is the value corresponding to x. What is the appropriate chart type? Any hints on the JSON data source? Thanks.
