I set the attribute color table of an intensity graph to a rainbow distribution of the colors, but now I'm not able to change the color table with the markers in the front panel. Do you know a solution?

Intensity graphs have two different modes for its color definition. The first, typical one, is the Color array. It can be set using either attributes or interactively and lets you define number/color pairs that create either a smoothly interpolated or a banded color gradient. The second mode is the color table. This is useful for bitmaps or for cases where the color table has been custom generated on the diagram. When using the color table, the Z scale is still useful for determining which numbers map to the 0-255 range of the color table. If you set the Z scale to autoScale, it will find the min and max of the data and set the Z to show all data mapped through the color table. If set smaller, some of the values will map to the first and last out of range colors. If set larger, it will map the values to a smaller and smaller number of the colors in the color table.
It sounds like you really want to be using the color array and not the color table. The intensity graph automatically switches for you when you write attributes to it, but there is a way to change it back the the color array using a popup or attribute.
