Method of Real-time Sampling
This section describes the real-time sampling method.
This method uses variable values acquired by the RAM monitoring function as the source data for the graph display. A conceptual diagram is shown below.
By default, the sampling-time interval is 500 ms. This interval can be set to as low as 100 ms. Let us try this now. Reduce the sampling interval by following the steps below.

In the debugging tool's properties, set the display update interval [ms] to "100", and run the program as before. Next, Stop the program. |

A line chart with a sampling interval of 100 ms appears in Analysis Chart . |
You can see that the plot interval is 100 ms, showing more fine-grained data than last time.
