Objet : R: RE: [Scilab-users] Issue with graphic interface
Yes, I'm using a GUI that perform operations on data and then displays the curve related to the processed data on a 2D plot.
The steps are very simple:
1) Load data files
2) Perform some operations on the data
3) Display the results on a 2D plot
At this stage of the process everything is fine and well formatted (since I set the properties of the figure and of the axis)
Now, It is useful however to compare different curves obtained with different data.
So I just repeat steps 1),2) and 3) in order to have a second plot on a different figure. When I copy and paste one curve (with the legend properly
formatted) in the box of the other curve I have to update the legend (and this is fine, for example in Matlab I usually do so). In order to update the legend I do the following operations
4) right click on one curve
5) "insert legend"
6) type the name of the curve
The fact that I don't understand is why when I update the legend (after step
6) the box of the legend (that has been set to be "white" in each of the two
figures) becomes transparent so that you can see the grid passing through the legend and making the legend itself not very clear to read.
Thanks for your help

</pre>
So: There are here 2 bugs:
<br>
a) the <span style="text-decoration: underline;">legends</span>
handle should not change
<br>
b) the fill_mode should not be set to "off". By the way, the default
is conveniently to "on". So it is not a default's issue.<br>
<br>
David, could you fill a bug report (i guess, only one)?<br>
