5. Viewing reports
The Graph Analyser displays interactive graphical and textual reports, and you can interact with these in a number of ways to get to the information you want. Each report has a few different options that are only relevant to that report, but they all share some features in common, as described in this section.
When you open a report, its file path is displayed in the title bar of the report window.
5.2. Adjusting report size
There are several ways to change the size and scale of the report in the Graph Analyser:
You can increase and decrease the display size of the entire application (including the Help window) by using the
Commandkeys with the
-keys to magnify and shrink the display size, just as you would in a web browser. There are three zoom options in the View menu that show the shortcut keys. Reset Zoom resets the magnification level back to its default setting.
To zoom in and out of a particular section of the graph, click and drag horizontally in the graph preview area above the main graph, and the display will change to show the graph that corresponds to that section of the data. A pair of limiter icons appear in the preview area to show the start and end of the data displayed in the main graph area. These can be dragged left and right to change the amount of data in the main graph. Using the scroll-wheel on your mouse scrolls the report page up and down, but you can zoom by holding down the
You can choose how you want your scroll wheel to behave (if you want it to scroll or zoom by default) by setting the Scroll behaviour preference.
You can also click and drag the main graph itself to view areas to the left and right of the currently viewed area. Note that clicking without dragging can sometimes select a specific tile (for example, in the Memory Report), but you can clear this selection from the input text box above the graph.
You can reset the zoom scale of the Memory and Liveness Reports by clicking on the small button to the left of the preview area, top-left of the graph. This zooms out to the furthest level, showing the entire graph.
To make a report larger, so that you can see more detail, you can drag the edges of the window to increase its size. This resizes the report images as you drag.
To adjust the space that each half of a report takes up on the page, click the splitter icon between the two halves of the report, and drag it up and down. The two report sections resize accordingly. Note that the Program Tree and Execution Trace reports also display a vertical splitter icon when comparing two reports, so you can choose how much of each report fills the available screen space.
5.4. Graph data keys
Below a graph plot are one or more keys with a coloured block and the name of the dataset that’s being plotted in that colour on the plot.
You can hover the mouse over a key to highlight the data plot on the graph that’s associated with that key (other data plots will be ‘greyed-out’).
You can click on a key to hide that dataset from the plot, and it appears with strike-through styling.
If you’re comparing two reports, there will be a set of keys for the source and the target reports. You can hover your mouse over a key, and the full path to that report is displayed.
5.5. Saving report images to disk
You can save report graphs to disk as image files or copy them to the clipboard, to avoid having to make screen captures.
Click on the camera icon in the top right-hand corner of a report.
Select whether to save to a file or copy to the clipboard.
If saving to a file, select the directory on your computer where you want to save it.
Messages are displayed if the image was successfully copied to the clipboard, or if failed to save to disk, depending on which choice you’ve made.
Report images are saved as PNG files, and capture the entire visible part of the report screen, including any detailed information displayed in the tabs below the graph. They also reflect the currently selected theme colours.
