Flickering colours and large X replacing temporal plot at some time steps in video #9

Open hallerth opened 8 years ago

Hello!

Im trying to create a movie of my results from a 2d-model of sea flooding. In the layout i have added three things, my results (with a sattelite photo in raster format as a background), a legend and a temporal plot of a point at my boundary (in a smaller window).

The results and the legend displays just fine but i am having problem with flickering colours at the bottom of the temporal graph (marked with a red dotted circle in attached image), also at some time steps the graph is replaced with a large cross covering the whole plot area. I have created around 10-15 movies and the error dissapears/ is more or frequent as i change the size and placement of the temporal plot area.

Is there any known way to avoid this issue?

Thanks!

Hi I think this particular comportment is related to the black area in your raster... As a first workaround, maybe you could extend your raster to avoid this black area. If you're familiar with Python, you could try to look into the code to find a cleaner solution. We will also have look on our side when we will found the time...

As a complementary remark, try to let the computer create the film as an alone task. Be sure to have no computation and don't do anything else... The cross appear when the image is not available so it means the plugin doesn't have the time to generate it before generate the image for the video...

Thank you for your fast response!

There seemed to be no difference in the display-problems as i moved the temporal plot around to different parts of the raster. However after a few runs and a few resizings of the temporal plot area it worked fine and I was able to produce a very nice looking video!

As far as the "cross problem" it worked much better when i stopped all my other tasks.

I tried to adjust the size of the axis labels but was not able to figure out if it was possible. If it is not possible i think it would be a very useful addition to the plugin. That way it would be possible to make sure that the numbers are clearly visible even when displaying the movies on a smaller screen (e.g. laptop).

Best regards
