[solved] Negative values

[whopix]

Hello, I'm from Russia, so sorry for the wrong English.
'm Here to whom you can talk about the negative values.
Who will tell the answer to my question, the script displays the data from -100 to +100, Cacti represents a positive, but when the script displays the values below 0, the graph is not displayed.
Be kind to answer this question, or who can offer an answer.
Thanks in advance.

The data template min DS size is too small (probably 0). you need to increase it in the template, then either run 'rrdtool tune' to adjust the DS size or delete the rrd file so cacti will recreate it with the new sizes.
