QUESTION
I really like how neat react-native-chart-kit is, however I am having a problem with how it display the data.
it use the lowest point in your data as the as the bottom and the highest as the top. There is an option to start from zero, but what if I wanted to start from 5? the same for the top, what If I wanted to display a range of 5to 90?
I was wondering if someone knew more about this graph or have used something else that can do these things?
Thanks
...ANSWER
Answered 2021-Jan-30 at 23:28A workaround is to do the following things:
- Use the
fromZero
prop on the chart; - Use a generator function that represents your custom y-axis label values;
- Pass the results the label generator function gives to the
formatYLabel
prop; - Adjust your data: Subtract your desired minimum label value from each number in your data set.
Example of the approach given above:

QUESTION
Snack I have a bar chart application with filters. I have included a side menu in the app. I need for the bar chart to display on the main screen and filters to display in the side menu. Currently, my bar chart is overlayering the side menu, like this-
I am not sure how to organize content on the main screen or the side menu. Maybe I am using the wrong package? The filters interact with the bar graph, that's why they can't be written out in different functions.
If viewing the snack, Clicking anywhere on the screen opens the side menu.

QUESTION
Snack I have created a bar chart in react native that enables users to make months selection and the chart renders according to their selection. However, what I have done so far is only changing the months labels on the x-axis. I am having issues implementing user selection on the bar graph itself. See below- The way variable datasets is defined, is the way how it was in the official documentation. Colors has to be defined for each bar line. I am thinking if somehow a for loop can be included there, according to the number of labels, the months filter would perhaps work. I am using applyDateFilter() to adjust labels in the chart.

QUESTION
Snack I have created a bar chart in react native that takes user input and adjusts accordingly. For instance, If user inputs Less Than 10, only bar components less than the user entered value show up. If user enters greater than 10, user entered value greater than 10 show up. The issue here is that the component instance is not rerendering post user selections. If I select less than 10 once, I cannot select less than 20 again the second time around. Bar component containing the value 20 is not simply there. Is there any way to make this barchart rerender everytime a user inputs a new value and selects a new less than/greater than picker option?
...ANSWER
Answered 2020-Nov-22 at 07:08First I think the logic inside applyFilter
is incorrect why?
datas
are the filtered data (in the first it's all records, but if you apply filters then datas
will be filtered records, so next time you use the filtered data, not all data) not all the data records, so you should have to keep all the records, somewhere and you cant change it, because you have to filter from the all of the records.
Then we should have a function to be called every time when lessThanOrGreaterThan
or filterLimit
change

following are the errors being returned 'Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.'
