plotSetYTicInterval
==============================================

Purpose
----------------
Controls the interval between y-axis tick labels and also allows the user to specify the first tick to be labeled.

Format
----------------
.. function:: plotSetYTicInterval(&myPlot, ticInterval[, firstLabeled])

    :param &myPlot: A :class:`plotControl` structure pointer.
    :type &myPlot: struct pointer

    :param ticInterval: the distance between y-axis tick labels.
    :type ticInterval: scalar

    :param firstLabeled: Optional input, the value of the first Y-value on which to place a tick label.
    :type firstLabeled: scalar

Examples
----------------

XY plot
+++++++

::

    // Create the sequence 0.25, 0.5, 0.75...3
    x = seqa(0.25, 0.25, 12);
    y = sin(x);
    
    // Declare plotControl structure
    // and fill with default settings for XY plots
    struct plotControl myPlot;
    myPlot = plotGetDefaults("xy");
    
    // Place the first Y-tick label at 0.5
    // and place additional ticks every 0.25 after
    plotSetYTicInterval(&myPlot, 0.25, 0.5);
    
    // Draw plot with applied Y-tick settings
    plotXY(myPlot, x, y);
