[Qgis-developer] Problems with Histogram tab in Raster properties

[Benoit de Cabissole]

 Hi,

A) In release 14370 the histogram tab of the raster properties window
has a problem:
The histogram is not displayed the second time the 'histogram tab' is
clicked.
E.g.:
1 - open the raster properties window
2 - click on the histogram tab
3 - histogram is computed and displayed
4 - click on any other tab
5 - click on the histogram tab again
6 - blank screen!!

On WinXP - OSGeo4W dev installation
Can someone replicate the problem?



B) And keeping with the histogram, three comments/suggestions:
- Could the NaN be excluded from the histogram?
- Could the X-axis numbers reflect the actual colour values instead of a
fixed 0-300 range?
   Note that the X-axis of the histogram is spread on colours values,
thus the displayed X-axis numbers are meaningless
- Could it be possible to add a zoom function on the histogram?


Best regards,
Benoit
