A version of Show that allows you to zoom in on a graphic using your mouse
Click and drag to select regions of a plot that you wish to see enlarged. Single-click to reset the zoom area:
In[1]:= | ![]() |
Out[1]= | ![]() |
The selected range can dynamically update a variable and the plot updates if the variable changes value:
In[2]:= | ![]() |
Out[3]= | ![]() |
You cannot use the mouse to resize the result of DragZoomShow, so it is is necessary to use ImageSize to control the size:
In[5]:= | ![]() |
Out[5]= | ![]() |
Within Dynamic or Manipulate plot ranges automatically reset with each refresh:
In[6]:= | ![]() |
Out[6]= | ![]() |
Specify a range variable to prevent automatic resets:
In[7]:= | ![]() |
Out[7]= | ![]() |
Zooming graphics with a fixed AxesOrigin may cause Axes not to be visible if the drag area does not cross the Axes:
In[8]:= | ![]() |
Out[8]= | ![]() |
In[9]:= | ![]() |
Out[10]= | ![]() |
Including AxesOrigin → Automatic in the DragZoomShow will cause Axes to be reconsidered after a zoom action:
In[11]:= | ![]() |
Out[12]= | ![]() |
The original graphic is not recomputed after a zoom action. This will cause a loss of sampling resolution:
In[13]:= | ![]() |
Out[14]= | ![]() |
Increasing the sample rate much higher than is initially visible will help:
In[15]:= | ![]() |
Out[16]= | ![]() |
Use the ResourceFunction DragZoomPlot instead to recompute the contents after zoom:
In[17]:= | ![]() |
Out[18]= | ![]() |
