Working with the Graph
To control the scaling of the axes and the appearance of plots, a set of commands and an axis scroll bar are provided. A data reader is also provided to facilitate reading data values in the graph.
Commands
|
|
Scale to Show All |
When checked, the x-axis is scaled to include all available data. |
|
|
Autoscale Right Side X |
When checked, the x-axis is scaled to include the time of the last data point. The left side of the x-axis is not automatically modified. This has the effect of condensing the contents of the graph whenever new data are added. |
|
|
Lock X-axis Range |
When checked, the x-axis is scaled to include the time of the last data point without modifying the length of the x-axis. This has the effect of scrolling the contents of the graph whenever new data are added. |
|
|
Connect GC Data |
When checked, data that are collected only at garbage collects is connected with lines. If the command is not checked, GC data are shown only as small circles. |
|
|
Include Zero |
When checked, the y-axes are scaled to include both zero and the highest value of the plots. If the command is not checked, the y-axes are scaled only to show the lowest and the highest values of the plot. |
Axis Scroll Bar
The axis scroll bar allows you to manually select the x-axis range of the graph. Below is an explanation of the different parts:
•
Left arrow
Clicking this part will scroll the x-axis one “step”
to the left. All autoscaling of the x-axis will be stopped when scrolling the
axis.
•
Left shaft
Clicking this part will scroll the x-axis one “page”
to the left. All autoscaling of the x-axis will be stopped when scrolling the
axis.
•
Left axis end box
Dragging this part will change the position
of the left side of the x-axis. If the axis scaling is set to “Scale to show
all” before dragging this box, the axis scaling will be changed to
“Autoscale Right Side X.”
•
Axis scroll box
Dragging this part will scroll the entire
x-axis to the left or to the right. All autoscaling of the x-axis will be
stopped when dragging the scroll box.
•
Right axis end box
Dragging this part will change the position
of the right side of the x-axis. All autoscaling of the x-axis will be stopped
when dragging this box.
•
Right shaft
Clicking this part will scroll the x-axis one
“page” to the right. All autoscaling of the x-axis will be stopped when
scrolling the axis.
•
Right arrow
Clicking this part will scroll the x-axis one
“step” to the right. All autoscaling of the x-axis will be stopped when
scrolling the axis.
Data Reader
The data reader can be used to read the value at a specific location of a plot. Simply move the mouse over a plot to read the value of the plot. When the cursor is close enough to a plot, a tooltip window will appear to the right of the graph, showing the name of the plot and the X- (time) and Y-value of the plot at the location of the cursor.
