+### Bug Fixes

+* graph might be wrong when using `attributes` if value was 0 ([e200323](https://github.com/RomRider/apexcharts-card/commit/e2003234f0b5a620c60a4a3e197c3b9577fd51ba))

+* yaxis would always start at 0 ([50ef9e4](https://github.com/RomRider/apexcharts-card/commit/50ef9e41d563d981b408382615c0939b7f330469)), closes [#158](https://github.com/RomRider/apexcharts-card/issues/158)
+* **group_by:** `group_by` reporting erronerous values for the first bucket of data ([8303b84](https://github.com/RomRider/apexcharts-card/commit/8303b84a935ed3f1a7c72642777052c487003e0f)), closes [#110](https://github.com/RomRider/apexcharts-card/issues/110)
