I am facing a slight issue when trying to get two decimal places after pasring double to string and trying to format
pieChart.setCenterText("$" + "" + "" +String.format( "% 1$ .2f", Double.toString(dataCost),""));
can anyone help me improve the above line of code so that it can display to two decimal places? You will also notice that I am trying to leave a space between the dollar sign and the value

String strDouble = String. format("%. 2f", 1.23456); This will format the floating point number 1.23456 up-to 2 decimal places, because we have used two after decimal point in formatting instruction %.
Just use %. 2f as the format specifier. This will make the Java printf format a double to two decimal places.
The %. 2f syntax tells Java to return your variable (value) with 2 decimal places (. 2) in decimal representation of a floating-point number (f) from the start of the format specifier (%).
2️⃣ f-string An f-string is a string literal in Python that has the prefix ' f ' containing expressions inside curly braces. These expressions can be replaced with their values. Thus, you can use f'{value: . 2f}' to return a string representation of the number up to two decimal places.
Following code might help you
double a = 1.234567;
double a = 2;
NumberFormat nf = new DecimalFormat("##.##");
System.out.println(nf.format(a));
System.out.println(nf.format(a));
and the output will be
1.23
2
it only show decimal places if needed, Enjoy! :)
