<p>This Sub calculates correct values for the following class local variables, if they have not been set by the user.</p>
<p>max_val, min_val: The maximum and minimum values for the y axis.<br/>
y_ticks: The number of ticks to plot on the y scale, including the end points. e.g. If the scale runs from 0 to 50, with ticks every 10, y_ticks will have the value of 6.<br/>
y_tick_labels: An array of strings, each is a label for the y axis.<br/>
y_tick_labels_length: The length to allow for B tick labels. (How long is the longest?) </p>
