+# Plot Acceleration
+
+The ``||led:plot bar graph||`` uses the screen to display magnitude of a value (positive or negative). 
+This is a great tool to understand the data returned by sensors... like the accelerometer.
+
+## Acceleration
+
+This example plots the acceleration in the ``x`` dimension on the LEDs.
+
+```blocks
+basic.forever(() => {
+    led.plotBarGraph(
+        input.acceleration(Dimension.X),
+        0
+    )
+})
+```
+
+## Console
+
+Click on the ``||Show Console||`` button to see a time chart of the value passed in the block.
+
+## Maximum value
+
+If you specify the maximum value, the block can do a better job at displaying the data. 
+For example, we can tell the block that we don't expect values beyond 1000 mg.
+
+```blocks
+basic.forever(() => {
+    led.plotBarGraph(
+        input.acceleration(Dimension.X),
+        1000
+    )
+})
+```
+
+## Other sensors
+
+You can use this block for pretty much any data. Try it out! We pass the light level to play with the light sensor. 
+
+```blocks
+basic.forever(() => {
+    led.plotBarGraph(
+        input.lightLevel(),
+        0
+    )
+})
+```
