dynazoom graphs should use full available height

[klaernie]

If dynazoom is available it should try to fill the whole usable area with graph values. That should be easy to compute, by getting the image size from a graph requested with e.g. 10px height, and subtracting this from the available height to compensate for the varying heights of the legend.

That's indeed easy to achieve, but there was a reason I kept the usual graph ratio: if you look at dynazoom graphs, the data granularity is really higher than standard graphs. This makes data less readable.

Then, if you make the graph height higher, this makes it even less readable! This example is a bit exxagerated, but you can see how it would look like.

This is still open for discussion for sure :)

Well, the example is well chosen. It's one of the 1s graphs, so it has a much higher update rate than the usual 300 seconds. Also it is a line graph, which makes it hard to read even in the default view.
But it get's the point across, there is no one way for all plugins. In this example the greater height leads to a better readability.
