The way to Modify X and Y Axis Scale in Arduino Serial Plotter (No Further Software program Wanted) – Open Electronics

The Serial Plotter in Arduino is a wonderful software for rapidly visualizing serial information. Nonetheless, it has a limitation that may frustrate many customers: it’s not instantly apparent alter the X and Y axis scales, particularly the X axis. On this article, I’ll information you step-by-step on remedy this challenge with out the necessity for added software program like Python or Processing.

Why Adjusting the Scale Is Essential

Within the newest model of the Arduino IDE (from model 2 onwards), the X-axis has a transferring scale that solely reveals 50 information factors, whereas the Y-axis is dynamic, adapting to the minimal and most values of the final 50 factors. This may make information interpretation troublesome, particularly if you happen to’re monitoring a secure sign comparable to a sine wave.
You possibly can do this code to expertise the visualization challenges:

float t; float y;
void setup() { Serial.start(115200); }

void loop() { t = micros() / 1.0e6; y = sin(2PIt); Serial.println(y); }

Steps to Modify the Axis Scales

1. Stabilize the Y-Axis

To maintain the Y-axis fixed, you possibly can add horizontal traces close to the specified minimal and most values. Right here’s do it:

float t; float y;
void setup() { Serial.start(115200); }

void loop() { t = micros() / 1.0e6; y = sin(2PIt); Serial.print("1.1, "); Serial.print("-1.1, "); Serial.println(y); }

2. Improve the X-Axis Scale

To switch the X-axis scale and show greater than 50 information factors, that you must edit a JavaScript file throughout the Arduino IDE. Right here’s proceed:

a. Find the JavaScript File

1. Entry the Program Recordsdata: Go to the folder the place the Arduino IDE is put in.
2. Navigate the Path: Observe this path: Assets > App > Lib > Backend > Assets > Arduino Serial Plotter Internet App > Static > JS [C:Program FilesArduino IDEresourcesapplibbackendresourcesarduino-serial-plotter-webappstaticjs].
   • If the trail doesn’t match, search the IDE folder utilizing the key phrase “plotter”.

b. Edit the primary.35ae02cb.chunk.js File

1. Create a Backup Copy: Copy the file primary.35ae02cb.chunk.js to the desktop for security.
2. Open the File in a Textual content Editor: Use an editor like WordPad or VS Code.
3. Discover the Line to Edit: Seek for useState)(50).
4. Modify the Worth: Change 50 to the specified variety of information factors. For instance, to extend it to 3000:
5. Save and Overwrite the Unique File: Save the modifications and duplicate the modified file again to the unique folder, changing the present file. Chances are you’ll must grant the required permissions.

3. Confirm the Adjustments

• Reopen the Serial Plotter: After saving the modifications, open the Arduino Serial Plotter once more.
• Examine the New Scale: The X-axis ought to now show as much as 3000 information factors.

4. Be Conscious of Limits

It’s vital to notice that there’s a restrict to the X-axis measurement, relying on the quantity of information you’re sending. In the event you set a price too excessive, you may discover that the plotter can’t show all of the factors. For instance, setting the X-axis to 5000 might trigger the plotter to cease between 3000 and 4000 factors resulting from information overload.

Conclusion

Adjusting the axis scales within the Arduino Serial Plotter can considerably enhance your information visualization expertise. By following the steps outlined above, you possibly can stabilize the Y-axis and enhance the X-axis scale, making it simpler to research your alerts. In the event you want a extra superior answer, think about using Python for an much more personalized visualization.
