<code class="function">SetYTickIncrement</code> sets the length of the interval between

Y tick marks (the tick increment, or tick step).

You can use either this function or <a class="xref" href="SetNumYTicks.html" title="SetNumYTicks"><span class="refentrytitle">SetNumYTicks</span></a>
|
|
|
6 |
(but not both) to control the tick mark spacing.

If neither <code class="function">SetYTickIncrement</code> nor
|
|
|
12 |
<a class="xref" href="SetNumYTicks.html" title="SetNumYTicks"><span class="refentrytitle">SetNumYTicks</span></a> is used, the tick interval
|
|
|
13 |
is automatically calculated by PHPlot.

|
|

See <a class="xref" href="adv-autorange.html#adv-autorange-tick" title="4.6.7. Automatic Tick Increment Calculation">Section 4.6.7, “Automatic Tick Increment Calculation”</a> for details.

|
|
|
16 |
Before PHPlot-6.0.0, if neither the number of ticks nor the tick increment
|
|
|
17 |
were specified, PHPlot calculated the tick increment as 1/10 of the X data
|
|
|
18 |
range.
|
|
|
19 |
Starting with PHPlot-6.0.0, a more complex algorithm is used which tries
|
|
|
20 |
to produce 'natural' tick increments.
|
|
|
21 |
</p><p>
|
|
|
22 |
Starting with PHPlot-6.0.0, if you call both <code class="function">SetNumYTicks</code>
|
|
|
23 |
and <code class="function">SetYTickIncrement</code>, the tick increment has priority
|
|
|
24 |
and the specified number of ticks is ignored.
|
|
|
25 |
Before PHPlot-6.0.0, the behavior was order-dependent: whichever function
|
|
|
26 |
was used last had priority.
