# graph temperature lesson
Create a charting app for simulating and measuring the actual temperature
## Topic
Acceleration
## Quick Links
* [activity](/lessons/charting/activity)
## Prior learning/place of lesson in scheme of work
Learn the functions of **on data received**, **send number** and **receive number** and chart `plot bar graph` for `acceleration` in the "x" dimension.
## Documentation
```cards
basic.showNumber(0)
input.acceleration(Dimension.X)
led.plotBarGraph(0, 1023)
radio.onDataReceived(() => {})
radio.sendNumber(0)
radio.receiveNumber()
```
## Objectives
* learn how to repeat code in the background forever
* learn how to get the acceleration value (g-force), in one of three specified dimensions
* learn how to display a vertical bar graph based on the value and high value.
* learn how to register code to run when a packet is received over radio
* learn how to broadcast a number data packet to other micro:bits connected via radio
* learn how to read the next radio packet as a number data packet

# charting activity
Measure the acceleration on the micro:bit in the "z" direction.
### ~avatar avatar
Welcome! This activity will teach how to use the 1st micro:bit to chart the second micro:bit's acceleration in the "x" direction. Let's get started!
### ~
Let's measure `acceleration (mg)` and then `send number`. `Acceleration` is measured in **milli-gravities**, so a value of -1000 is equivalent to -1g or -9.81m/s^2. We will be able to get the acceleration value (g-force), in the specified "x" dimension. `Send number` will broadcast a number data packet to other micro:bits connected via radio.
```blocks
radio.sendNumber(input.acceleration(Dimension.X));
```
### ~
We want to display the acceleration forever. In order to do so, we need a `forever` loop. A forever loop will repeat code in the background forever.
```blocks
basic.forever(() => {
radio.sendNumber(input.acceleration(Dimension.X));
});
```
### ~
We want to register code to run when a packet is received over radio. We can implement this code by adding `on data received`.
```blocks
basic.forever(() => {
radio.sendNumber(input.acceleration(Dimension.X))
})
radio.onDataReceived(() => {
})
```
### ~
Finally, we want to chart the acceleration. So we must first implement `plot bar graph`. `Plot Bar Graph` will display a vertical bar graph based on the value and high value. In order to transfer the receive the number from the 1st micro:bit, we must implement `receive number` to constantly display a vertical bar graph based on the value. Remember, the value will equal to the micro:bit's acceleration in the "x" direction.
```blocks
basic.forever(() => {
radio.sendNumber(input.acceleration(Dimension.X))
})
radio.onDataReceived(() => {
led.plotBarGraph(radio.receiveNumber(), 1023)
})
```
### ~
Notice that moving the micro:bit the farthest direction in the x direction will be -1023 on the charting beneath the simulator. The second observation will be that the LEDs will be full brightness on the 2nd micro:bit. There is a single LED turned on with the 1st micro:bit. Additionally, the graphs will reflect 0 acceleation for the 1st micro:bit. In this scenario, if you are adjusting the acceleration in the simualator, you are also changing your chart that will be produced.

### ~
NOTE: The colors of the charts reflect the color of the micro:bit simulator. In this instance, the micro:bits are blue and green. So the colors of the line graphs reflect the colors of the micro:bit
### ~
After running this simulatation several seconds by moving the micro:bit side to side in the x direction, you are ready to graph or chart the accceleration of the micro:bit. We want a printout of our acceleration on Excel. We will graph the fluctuating acceleration of the simulation experiment.

### ~
Finally, you must open the Excel CSV file by clicking on the data.xls file that was downloaded to Downloads Folder.

Have fun reviewing your simulation and analyze the acceleration by chart the Excel data using Excel.
* Connect the first micro:bit to your computer using your USB cable and run the charting script on it.
* Connect the second micro:bit to your computer using your USB cable and run the charting script on it.
* The first person and second person take turns tilting the micro:bit in the "x" direction while the other player charts the data on the micro:bit!
* Review and analyze the actual micro:bit device acceleration data on Excel
