Having top grid lines above highest value in all graphs
This is something that I guess we discussed already as part of #30 (closed), but I still see it happening. It would be great to have a grid marker above highest value in the graph. This is how it looks like now:
The maximum value is 25 198 bud the highest grid line is 24 000. Especially with graphs where top value is on rightest side, for some people that don't expect this behavior it may look like the top value is something between 20 000 and 24 000 because they don't see grid line for 28 000. Even those that pay attention that top grid line is missing they may hardly guess how far behind the grid line for 24 000 it is because they don't see top grid line to have some visual comparison. This is particularly important for exported graphs when there is not possibility to point mouse to reveal the values.
