5447 Bug/feature? Random functions in plot views

[ColinJDenman]

When viewing plots that are based on symbolic entries involving random functions, I find the values seem to be re-evaluated whenever I alter the cursor position, although the plot (fixed-line segments or adaptive) remains the same. The cursor position seems to be unrelated to the plotted graphs.

Similar altered values in numeric view seem to suggest the values are recalculated at any opportunity. This helps with non-random functions to update the display, but when a random value is involved, it isn't updating the display fully and is in any case a bit inconvenient for examining the plots (zooming in etc.).

It seems one might have to generate the randomized data outside the plotting app, store it in a variable, then plot the variable in order to examine the data without interference.

Perhaps the data should be calculated on pressing the plot or numeric button, but not updated unless specifically requested by another keypress? Perhaps a plot/numeric settings feature?
