Bar Graph display

Compare manually-sampled measurements across categories.

Displaying data in a bar graph is useful when you want to compare a single sensor measurement between different categories, such as measuring the pH of several different chemicals. If you want to compare values across multiple sensors of the same type of measurement, a bar meter display would be more appropriate.

  1. Y-Axis Variable

    Click to select a measurement to display on the y-axis. This is typically a sensor measurement.

  2. Y-axis

    Drag to manually scale the y-axis.

  3. Bar name

    Click the bar above the bar name to change the name.

  4. Bar Graph tools

    • Scale to Fit

      Click to scale the graph to fit all of the data.

    • Statistics

      Click to display statistics for the current run such as maximum, minimum, mean, and standard deviation.

    • Annotation

      Add a note to a bar. Click to turn on the tool then click a bar to add a note to.

    • Show Digits

      Click to show the digits of the measurement above each bar.

    • Show Next Bar

      Click to show the next bar. Click this bar to add a new data point when displaying user-entered data on the Y-axis.

    • Add a Run

      Click to add a new run of data. This is only active when the Y-axis is displaying user-entered data.

  5. Manual entry

    Manual sampling is automatically selected when using a bar graph. After selecting Start to begin data collection, select Keep to record a measurement.

  6. Legend

    Use the legend to identify, display, and select runs to analyze. Select the checkbox to show or hide runs. For analysis, the selected run is indicated by a red box.

  7. X-Axis Variable

    Click to select a measurement to display on the x-axis. This is typically user-entered data.

Collect data

  1. Select Y-Axis Variable, then select a measurement to display on the y-axis.

  2. Select X-Axis Variable. The X-Axis variable is typically user-entered data, which means you need to create a User-entered measurement:

    1. Select the User-entered tab.
    2. Select Create Data Set.

    3. Enter a Measurement Name for the Data Set, then select OK.

      Note

      You can also configure the other Data Set options, but it is not required.

  3. Select Start to begin data collection.

  4. Take a measurement with your sensor. Once you are done with the measurement, select Keep to record the measurement. A second bar now appears.
  5. Repeat the previous step for all of your data samples. Click Stop when finished.
