Plotting range vs. display range
The plotting range is the range of the independent variable (or variables)
over which the current equation is evaluated. If you don’t specify the
plotting range, the HP 49G uses the a;-axis display range (specified by
XRNG or by H-VIEW) as the plotting range. However, you can specify a
plotting range that is different from the ir-axis display range:
• For polar and parametric plots, the independent variable isn’t related
to the x-axis variable; therefore you specify the plotting range to
control the range of the independent variable.
* For truth and conic plots, you can shorten plotting time by specifying
plotting ranges that are smaller than the x- and y-axis display ranges.
These plot types require you to specify the dependent variable. You can
specify a plotting range different from the ?/-axis display range.
You can make PICT larger than its default size (131 by 64 pixels) and
either keep the same x and y scale factors (which extends the display
range), or keep the same display range (which extends the scale and
appears to stretch the plot.
To check the current size oF PICT
1. Press o (Rty to select the Recall command.
2. Type PICT.
3. Press
The message “Graphic width x height” is returned, indicating the
current dimensions of PICT.
In RPN mode: follow steps 2 and 1.
To change the size oF PICT
To keep the same scaling:
1. Press 0 (ED PICT PDM to select the pict dimension command.
2. Enter a complex niunber to indicate the coordinates, in user imits, of
one comer of PICT.
3. Press 0Q.
