Web app to plot data to chart based on date & time.
Budget: $10 – $35 USD
I am looking for a web app developer to create a web app that will plot numerical data to a chart based on date and time.
Need to make a web app compatible with Mobil and PC users that plots the provided data to a chart.
Data will be downloaded to users device (data.txt ) , users open the web app loads the file , then data gets populated to chart.
This is part of a data logger project.
I use ESP32 controller to get data from an engine ECU, data is stored on an SD Card on a file called data.txt. Data is arranged by date/time a separator then the encoded data.
I currently have it working as part of the data logger.
It’s an option where the users can open if they want to see the history (data stored). Problem with it is that can only read and plot 70 - 90 data points.
Some of these files could be 1440 data points.
If data is saved every minute, that’s 60x24 =1440 a day!
Maybe add a way user can see data from a specific date instead of plotting the whole file.
Let me know if you have a better solution!
