|
|
|
9 |
By default, the X axis line is drawn.
|
|
|
10 |
</p><p>
|
|
|
11 |
Disabling the X axis line does not disable associated plot elements, nor
|
|
|
12 |
change the plot margin calculation. To produce a completely 'bare' plot,
|
|
|
13 |
you must turn off the grid, tick marks, tick labels, and data labels. You
|
|
|
14 |
also need to turn off the plot area border, which defaults to left and
|
|
|
15 |
right sides. Lastly, you might want to reduce the margins, since the
|
|
|
16 |
default minimum margin is 15 pixels on each side of the plot area, even if
|
|
|
17 |
there are no axis lines, labels, or titles. Here is an example:
|
|
|

|
|

25 |
$plot->SetDrawXGrid(False); // Turn off X grid lines

$plot->SetDrawXAxis(False); // Don't draw X axis line
|

28 |
$plot->SetDrawYAxis(False); // Don't draw Y axis line
|
|

29 |
$plot->SetMarginsPixels(2, 2, 2, 2); // Reduce plot margins to 2 pixels

See <a class="xref" href="ex-truecolor-histogram.html" title="5.24. Example - Using Truecolor To Make a Histogram">Section 5.24, “Example - Using Truecolor To Make a Histogram”</a> for an example of a plot
|
|
|
33 |
where axis lines are not desired. (The configuration data as shown
|
|
|
34 |
in the example draws a full plot area border, so the axis lines would be
|
|
|
35 |
covered anyway. But if the border is turned off, the axis lines would be
|
|
|
36 |
visible unless they are suppressed as shown.)
