Before you begin

You need permission to:

• view robotic.sensor_data;
• create charts;
• save content, if you want to keep the result.

If the source is missing, do not choose a similar name. Ask for access to the correct source.

1. Choose the source and line chart

1. Open Charts.
2. Click + Chart.
3. Search for sensor_data under Data source.
4. Select Line chart.
5. Click Create new chart.

Do not continue until both selections are active.

2. Recognize Explore

Explore has three areas:

1. Source, on the left: available columns and metrics.
2. Configuration, in the center: time, metric, filters, and appearance.
3. Preview, on the right: the query result.

The preview does not change after every edit. Click Create chart or Update chart.

3. Complete the four controls

Control	Value in this example	What it does
X axis / Time column	timestamp	Places each reading in time.
Time grain	Minute	Groups readings so the curve stays readable.
Metric	CPPW	Selects the sensor value to measure.
Time range	Today	Limits the query to the current day.

Complete the controls in the center; the preview appears on the right.

Do not confuse time grain with range

Time grain groups points—by minute or hour. Range decides the period—today or last week.

4. Run and wait

1. Confirm no required field has a red mark.
2. Click Create chart.
3. Wait for the button to change to Update chart.
4. Do not save while the screen says Loading.

5. Validate the result

Ready result: the line is drawn, the axis shows the period, and the row count is visible.

Check three things:

• Processed rows exist. The count confirms the query returned data.
• The line is visible. No empty area or loading state remains.
• The axis is correct. Hours match the range you selected.

Resultado esperadoExpected result

CPPW appears as a continuous or segmented line, the row count is visible, and the horizontal axis matches today.

If the curve has too many points

• Change the time grain from Minute to Hour.
• Or reduce the time range.
• Update again and compare readability, not only speed.

Next, save the chart and add it to a dashboard.
