SVG Error: error while updating property of 'd'

156 views Asked by At

Before i start i just want to mention that i tried some ways of solving this problem when i search the site for answer, couldn't make this work :(

As the title suggested i have a problem while i'm using React Native Victory graphs. To be clear: it works fine untill i press the button to display the graph again.

for example this is the onPress im calling the graph with useState method:

<TouchableOpacity
      onPress={() => {
        setBarChecked(true);
        setLineIsChecked(false);
        setLineChecked(false);
        setPieChecked(false);
      }}
    >
      <FontAwesome5 name="chart-bar" size={36} color="#0000FF" style={{ padding: 9 }} />
    </TouchableOpacity>

This is the graph code:

    <VictoryBar
      barRatio={0.8}
      style={{
        data: { fill: "#c43a31" }
      }}
      data={handleBarData()} //This function calculate data and return array
    />

After a graph icon is pressed its working [![Working][1]][1]

After im pressing another graph, and then returning to graph i already pressed before, the app freeze and i get this error:

[![error][2]][2]

using "react-native-svg": "^12.1.0",

Edit start here:

HandleBarData():

  const handleBarData = () => {
    //Predicion Part Start here -----> Bar Graph!!//

    const fictionalIncome = [560, 150, 3870, 4000, 7860, 7840]; // Past Values
    const size = fictionalIncome.length;

    let i = 0;
    const diffrence = [];
    for (i; i < size; i++) {
      diffrence[i] = arrayIncome[i] - fictionalIncome[i];
    }
    //console.log("Diffrenec => ", diffrence);

    let j = 0;

    }
    //console.log("Power => ", difWithPower);
    ///////////////////////////////////////////

    let k = 0;
    const substract = [];
    for (k; k < size; k++) {
      substract[k] = difWithPower[k] - 1;

    let h = 0;
    const growthRate = [];
    for (h; h < size; h++) {
      growthRate[h] = substract[h] / 100;
    }
    //console.log("Growth Rate => ", growthRate);

    let a = 0;
    const resultIncome = [];
    for (a; a < size; a++) {
      resultIncome[a] = parseInt(
        diffrence[a] * growthRate[a] + diffrence[a],
        10
      );
    }

    //console.log("Difference X Gr Rate => ", resultIncome);

    //Graph of Future Income Start here ----->//
    let nextYearMonths = [
      "Jan 21",

      "May 21",
      "Jun 21",
    ]; //Present first 6 Months of the year.
    const futureIncome = resultIncome; //[348,53,1291,226,1306,424];

    const result = {};

    nextYearMonths.forEach((key, i) => (result[key] = futureIncome[i]));
    const barData = { ...result };

    const arr4 = new Array();
    for (const [key, value] of Object.entries(barData)) {
      arr4.push({ x: key, y: value });
    }
    console.log("Arr 4 ", arr4); //Fetch to Graph?

    return arr4;
  };

Console Log:

Arr 4  Array [

I think this happens when you pass no data to your SVG graphs in Android. iOS does not have this issue.

Please make sure handleBarData() is always returning data to display on Android. If no data is present don't show your graph or it will crash. Something like this:

// Assuming your data looks like this
const data = [
  {
    month: 'Jan',
    count: 200
  },
  ....
]

const data = handleBarData()
const isDataAvailable = !!data.find(el => el.count > 0)
if (!isDataAvailable) {
  return <NoData/>
}

return <MyGraph/>

If the above is not working for you, please add a console.log() screenshot of the result of handleBarData() here so I can see what is going on.


Edit: Ok I have still the same hunch and I would do the following. Instead of passing data as a function like so data={handleFirstLine()}, assign every data function to a variable: const firstLineData = handleFirstLine(). Then console.logthat data and make sure that data IS available (i.e. that x > 0) . This issue happened to me and was very frustrating.
