Useful improvements to graphs
I have noted two desirable amendments to graphing functions in 2.1 20060515
1) When I edit a formula for Point Labels in the Format toolbox, Chart tab, the edit box has a bug that moves the cursor to the last character whenever you insert a single character.
2) With point label formulas, I try to set “dynamic” point labels on the horizontal axis, for example marking threshold levels or adding some text, or simply in order to control the scaling of shown values. In order to do that I set a formula returning some value or text at given intervals (1 out of 10 items e.g.) or under given conditions, and an empty string otherwise. Well, I have noticed that labels’ display is strictly controlled in order to avoid overlap of contiguous values, but in my opinion the effect is too restrictive, even with vertical orientation of text, and what is shown depends on the width of the graph or other contingent circumstances: would it be possible to add a setting forcing the display of all labels, leaving to the user the cleaning of overlaps?
I have reproduced the bug with the following steps, after opening the formula edit dialog for point labels;
1) enter something in the 1st argument of an if() function, e.g. if([some category]=0
2) enter “;” or “,” (I use the IT locale)
After that, the cursor shifts at the end of the line and any subsequent key pressed has the same effect.
Hope this helps.
