The plugin builds any number of math graphs, locates its intersections and extremes, makes the report.

Below are some tips you may find useful when using the plugin:

To show the GraphBuilder plugin use Ctrl+G shortcut.
To add formula to GraphBuilder plugin just click on it in the Notepad++ edit area.
To show the left panel of plugin press right arrow while holding down Ctrl.
To hide the left panel of plugin press left arrow while holding down Ctrl.
To show the bottom panel of plugin press top arrow while holding down Ctrl.
To hide the bottom panel of plugin press down arrow while holding down Ctrl.
To gently increase or decrease the value in some of text edit field (if possible), just place cursor on it and move wheel on mouse.
To move the graph area simply click it and drag at the desired position.
To zoom in or zoom out simply move wheel on mouse when holding cursor on graph area. The new graph will be rebuilded and cenetered at the cursor position.
To share the current math graphs, simply copy it by pressing "Copy" button. It places some short text in the clipboard which is suitable for sharing.
To restore the math graphs from text data, received from the outside, simply place that text in the clipboard and press "Paste" button.
There is a bookmark panel on the top side of the plugin. To save the current math graphs - simply press at the any of unused bookmark button. To restore the previously saved math graphs - simply press the same bookmark button again. Please note that the restoring causes the bookmark button becomes unused and associated data is lost.
For the benefit of comfort there are two variables available to use within the formula: X in rectangular coordinate system and T in polar coordinate system. However both of them are interchangeable.
Below is the list of functions that can be used to construct the formula:
