Description

Graph tracks can have regions with value=0.
One of the graph track operations is the inverse function, and several other functions include an inverse.
But the inverse of 0 is infinity.
IGB needs to handle this.

Currently, if you take the inverse of a graph track where the value is 0, the y-max for the resulting track is set to 340282346638528860000000000000000000000, and the values on the Y-axis end in "Y", and all the values that have legit values are squished down to be invisible, so the entire track appears blank.

The inverse function just needs to have a catch to handle this. If input is 0, output is NA.

To replicate in IGB:
1) Open human genome (H_sapiens_Dec_2013)
2) Navigate to: chr1:0-550
3) Load the two attached files (graphWithNoZero.bedgraph and graphWithZero.bedgraph) into IGB and load their data.
4) Click the graphWithZero.bedgraph track label to select it.
5) Under the Graph tab within the Operations section, change the Single-Graph dropdown to Inverse and click Go.

Note that this will max out the value of the zero values to 340282346638528860000000000000000000000.
Repeat the same steps for the graphWithNoZero.bedgraph file to observe how the graph should appear.

Tested on mac using 1344 dmg installer from Supreeth's branch.

Tested using attached test files. Working correctly.

Sai Supreeth Segu ready for pull request.

Tested on release 9.1.6 on Mac using the attached bedgraph files.

Applying inverse to a value of 0 in the graph operations now results in a value of infinity.

Closing issue.
