<H3><A NAME="8_3_3">8.3.3 Adjusting the grid lines</A></H3>
<P> As usual you have full freedom to select what grid lines you like to
 show (and what colors they should have). There are three different
 types of grid lines you may adjust. The radius minor and major grid
 lines and the angle grid lines.</P>
<P> You select what grid lines to show with a call to <A href="../ref/PolarAxis.html#_POLARAXIS_SHOWGRID">
PolarAxis::ShowGrid()</A> The two example below shows a logarithmic plot
 with either just major grid lines or both minor and major grid lines.</P>
<P><DIV class="example">
<BR> <A href="exframes/frame_polarex4.html" target="blank"><IMG border="0"
HEIGHT="350"       src="img/img/img/img/img/img/polarex4.png" WIDTH="300"></A>

<P> The colors of the grid lines are specified with a call to <A href="../ref/PolarAxis.html#_POLARAXIS_SETGRIDCOLOR">
 PolarAxis::SetGridColor()</A></P>
<P> For the angle grid lines it is possible to specify the angle
 division between each grid line with the method <A href="../ref/PolarAxis.html#_POLARAXIS_SETANGLESTEP">
 PolarAxis::SetAngleStep()</A> You specify the step distance in degrees.
 By default the step size is 15 degrees.</P>
