This can be done using Graphical Analysis Pro or Logger Pro<\/em>.<\/strong>
This cannot be done using the free version of Graphical Analysis.<\/p>\n

In Graphical Analysis Pro and Logger Pro<\/em>, you can display a meter for any calculated column. To show a meter that displays the maximum value obtained by a sensor during data collection, you need to use the function max(X) as the expression for your calculated column. <\/p>\n

Note:<\/strong> This same method can be used to create meters for any statistic that creates a single value in your data table, such as minimum [min(X)], average [ave(X)], and standard deviation [stddev(X)].<\/p>\n

Graphical Analysis Pro<\/h3>\n
    \n
  1. Launch Graphical Analysis Pro and connect to your sensor.<\/li>\n
  2. Click or tap the y-axis label to display the Plot Manager.<\/li>\n
  3. Click or tap the three-dot icon, \"\", next to the sensor column name, and select Add a Calculated Column<\/strong>.<\/li>\n
  4. Enter a name and units, and adjust the displayed precision as desired. Verify the Metered option is selected.<\/li>\n
  5. Click or tap Insert Expression<\/strong>, then click or tap Custom Expression<\/strong>.<\/li>\n
  6. Enter the expression max(“X”)<\/strong>, where X is replaced by the name of the column showing the sensor data.*<\/strong><\/li>\n
  7. Click or tap Apply<\/strong> to create the calculated column.<\/li>\n
  8. To display the meter, click or tap View Options, \"\", and turn on Meters.<\/li>\n<\/ol>\n
    <\/div>\n

    Logger Pro<\/em><\/h3>\n
      \n
    1. Launch Logger Pro<\/em> and connect your sensor.<\/li>\n
    2. Choose New Calculated Column<\/strong> from the data menu.<\/li>\n
    3. Enter a name, short name, and units.<\/li>\n
    4. Enter the expression max(“X”)<\/strong>, where X is replaced by the name of the column showing the sensor data.*<\/strong><\/li>\n
    5. Click or tap the Options tab and adjust the displayed precision as desired.<\/li>\n
    6. Click or tap Done<\/strong> to create the calculated column.<\/li>\n
    7. To display the meter, choose Meter > Digital Meter<\/strong> from the Insert menu.<\/li>\n
    8. Choose Auto Arrange<\/strong> from the Page menu to optimize layout of the screen with the new meter.<\/li>\n<\/ol>\n
      <\/div>\n
        <\/ul>\n

        *<\/sup><\/strong> For example, if your sensor column name is Temperature<\/strong>, the expression would be max(“Temperature”)<\/strong>.<\/p>","protected":false},"excerpt":{"rendered":"
