Count Measure category in Donut Chart

I don't know a easy way to supply sample data.

I have 3 tables;

1: Object information;     Id, address, gas_ID, heat_ID

2: RegisterID;     gas_ID / heat_ID, address, type (gas or heat) (there is a relationship with Object info based on address)

3: Usage;     Date, gas_ID / heat_ID, usage; also a couple of calculated columns to seperate the gas and heat usage

Table 3 has a relationship with table 2 based on gas_ID/heat_ID

In the table 3 I have the following measures:

YieldPercentage = IFERROR( (sum(heat usages)/sum(gas usage));0)

PercentageCategory = if(or(ISBLANK([YieldPercentage]);[Rendement%]=0);"Blank";     if([YieldPercentage]<0,80;"<80%";   if([YieldPercentage]<0,85;"80-85%";     if([YieldPercentage]<0,9;"85-90%";      if([YieldPercentage]<1;"90-100%";">100%")))))

For the column chart I have the following measures:

<80% = IFERROR(if([YieldPercentage]<0,8;[YieldPercentage];0);0)

80-85% = IFERROR(if(and([YieldPercentage]<0,85;[YieldPercentage]>0,8);[YieldPercentage];0);0)

85-90% = IFERROR(if(and([YieldPercentage]<0,9;[YieldPercentage]>0,85);[YieldPercentage];0);0)

90-100% = IFERROR(if(and([YieldPercentage]<1;[YieldPercentage]>0,9);[YieldPercentage];0);0)

>100% = IFERROR(if([YieldPercentage]>1;[YieldPercentage];0);0)

I made a measure for every category so I could determine the colours of the bars.

Please let me know how I can give better/more informatie without showing actual customer data
