Expected behavior

I will like to make some Charts & Minimalist Charts for my web in dynamically. So my question is how to make the charts component that can change the value overtime in real-time dynamically based on the database I have in MySql Server. If my database change, the charts values also can change in real-time.

Would you please help and advise me step by step to achieve that and what are the requirement should I follow? I am appreciated your kind assistance. Thank you very much.

Actual behavior

Right now the charts and minimalist-chart that I have are just static.

Resources (screenshots, code snippets etc.)

Hi @cokicoki,

In the examples you have written, you must use the same code as in the sample I wrote above.

You need to use state:

 state = {
    yourVariableName: 10
  };

Function to change the state.

  handleChange = e => {
    this.setState({
      yourVariableName: e.target.value
    });
  };

Charts props:

percent={this.state.yourVariableName}

That's all you need to do to make your charts dynamic.

Best Regards,

Kuba

Would you mind and please also give the other snippet charts for : Line chart, Radar chart, Bar chart, Polar Area Chart, Pie Chart, Doughnut Chart as I use them a lot on my web.

Hi @cokicoki,

Unfortunately, I can not help you with your database but I wrote a simple snippet to show you how to change dynamically value of the MDBSimpleChart. You should only replace my variable to your data from MySql.

import React from 'react';
import {
  MDBContainer,
  MDBRow,
  MDBCol,
  MDBSimpleChart,
  MDBInput
} from 'mdbreact';

class ChartsPagePro extends React.Component {
  state = {
    variable: 10
  };

  handleChange = e => {
    console.log(e.target.value);
    this.setState({
      variable: e.target.value
    });
  };

  render() {
    return (
      <MDBContainer>
        <h3 className='mt-5'>Minimalistic charts</h3>
        <div style={{ marginTop: '100px' }}>
          <MDBContainer>
            <MDBRow className='text-center'>
              <MDBCol sm='4'>
                <MDBSimpleChart
                  width={100}
                  height={100}
                  strokeWidth={3}
                  percent={this.state.variable}
                  strokeColor='#4FB64E'
                  labelFontWeight='300'
                  labelColor='#000'
                />
                <MDBInput type='number' onChange={this.handleChange}></MDBInput>
              </MDBCol>
            </MDBRow>
          </MDBContainer>
        </div>
      </MDBContainer>
    );
  }
}

export default ChartsPagePro;

If there is anything else I could do for you do not hesitate to ask me. I'll be happy to help you.

Best Regards,

Kuba
