TIMEPLOT: Scaling is broken when all values of an axis are negative #80

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
When you have an axis where all values are negative (below zero), then
scaling is broken.
min: and max: are also ignored then.

Examples:
The Plot looks like shown in this image when all values are negative:

If i add one positive Value, the Graph is drawn correctly:

Here are my DataRows:

Data which produces the erroneous graph:
2007-08-01 00:00:00,-0.0185,0.0208,-0.0264
2007-08-01 12:00:00,-0.0185,0.0228,-0.0264
2007-08-02 00:00:00,-0.0195,0.0218,-0.0224
2007-08-02 12:00:00,-0.0175,0.0198,-0.0304

Data which produces the correct graph:
2007-07-31 23:59:59,0.001,0.001,0.001
2007-08-01 00:00:00,-0.0185,0.0208,-0.0264
2007-08-01 12:00:00,-0.0185,0.0228,-0.0264
2007-08-02 00:00:00,-0.0195,0.0218,-0.0224
2007-08-02 12:00:00,-0.0175,0.0198,-0.0304

What can i do to get the scaling working correctly, without modifying my data?
